When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 3b - 4b = 7b + 3z + 5 for b in terms of z.
| -1\(\frac{3}{4}\)z - 1\(\frac{1}{4}\) | |
| -\(\frac{1}{10}\)z - \(\frac{1}{10}\) | |
| -7z + 2 | |
| \(\frac{7}{10}\)z - \(\frac{2}{5}\) |
